Dr. Kohei SOGA started his research on rare-earth-doped luminescent materials in 1990 as a graduate student of the University of Tokyo. His thesis concentrated on relating the spectroscopic properties of the rare earth ions and the structure of the host glass. After obtaining the Ph. D. degree in 1995, he explored his research onto the photonic applications, especially on that relating to optical communication. Beside the work on physical properties of icosahedral cluster solids started in 2000, he has extended the materials to nanophoshpors. Since 2004, he has challenged to develop biophotonic system under infrared excitation as an interdisciplinary research by bio-nano-photonics collaboration. The research is attracting the interests from the researchers in medicine, biomaterials, photonic materials and bioengineering.

He has authored and co-authored over 90 journal papers and presented 17 invited, 191 oral and 73 poster presentations.
